J0201-1-1 Occupant Injury Protection in Frontal Car Crash by Using Shoulder Belt and Lap Belt Control

Abstract

This paper investigates occupant injury protection in frontal car crash. The occupant is modeled as three lumped masses. An active shoulder belt and an active lap belt are used to control occupant's motion. We assume that the shoulder belt force acting on the torso is controlled by the active shoulder belt, and that the lap belt force acting on the pelvis is controlled by the active lap belt. The control problem is formulated as an optimization problem. Numerical simulations show that the cooperative control of the active shoulder belt and the active lap belt reduces the maximum deceleration of the torso.
